調用SetRegistrationListener時發生空指針異常

在擴展了線程的類內sipmanger.open後調用以下內容。我檢查了是否有任何參數爲空，但它們不是。調用SetRegistrationListener時發生空指針異常

任何想法？

private void setlisten() throws SipException { 
    sipman.setRegistrationListener(sipprofile.getUriString(), new SipRegistrationListener() { 

     public void onRegistering(String localProfileUri) { 
      Message msg = Message.obtain(); 
      msg.what = 10; 
     } 

     public void onRegistrationDone(String localProfileUri, long expiryTime) { 
      Message msg = Message.obtain(); 
      msg.what = 93; 

      Log.d("register", "register done"); 
     } 

     public void onRegistrationFailed(String localProfileUri, int errorCode,String errorMessage) { 
     }  
    }); 
}

堆棧跟蹤是休耕：

153行：

sipman.setRegistrationListener(sipprofile.getUriString(), new SipRegistrationListener() {

線193：

setlisten();

private SipProfile buildsip(JSONObject sipcreds) throws JSONException, ParseException{ 

    SIP_USER = sipcreds.getString("username"); 
    SIP_PASSWORD = sipcreds.getString("password"); 

    if (sipman == null){ 
     sipman = SipManager.newInstance(context); 
    } 

    SipProfile.Builder builder = new SipProfile.Builder(SIP_USER, SIP_DOMAIN); 
    builder.setPassword(SIP_PASSWORD); 
    builder.setAuthUserName(sipcreds.getString("username")); 
    builder.setAutoRegistration(true); 
    builder.setOutboundProxy(SIP_DOMAIN); 

    SipProfile mSipProfile = builder.build(); 

    if (mSipProfile == null) { 
     Log.d("problem", "that seems to be the problem"); 
    } 


    return mSipProfile; 
} 


private void sipint(SipProfile sipprofile) throws SipException{ 

    Intent intent = new Intent(); 
    intent.setAction("android.example.project2.INCOMING_CALL"); 
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, Intent.FILL_IN_DATA); 
    sipman.open(sipprofile, pendingIntent,null); 

    if (sipman == null){ 
     Log.d("problem", "found the null"); 
    } 

SipProfile sipprofile = buildsip(sipcreds); 

     sipint(sipprofile); 
     setlisten();

如果你正在得到一個NPE，你能發佈logcat嗎？因爲* *是* null。 – codeMagic

您可以添加NullPointerException的堆棧跟蹤嗎？ – icyitscold

什麼是第153行？ – codeMagic

仔細檢查變量sipman和sipprofile不是null。

完成它們不是 – user155813

請mmh請分享您的logcat和引發異常的行 – ssantos
